Product Description

The ZGS11-10 is an important power supply unit in urban cable distribution networks, integrating high-voltage control, protection, transformation, and distribution equipment into a complete pre-installed product. It is widely used in urban and rural power grids.

This product places high-voltage load switches and high-voltage fuses in the transformer oil tank, and is available in two configurations: a single tank with the transformer body or separate tanks. The oil tank uses a fully sealed structure, equipped with oil temperature gauges, oil level gauges, pressure gauges, pressure relief valves, and oil drain valves to monitor transformer operation.

The product is available in ring network, terminal, and power supply modes. To better adapt to the actual requirements of China's power grid, the company has launched plug-in dry-type fuses whose melting does not affect transformer performance. Based on the complexity of low-voltage outlet requirements, the ZGS11-10 product is divided into standard, reinforced, and comprehensive types, allowing users and design units to select models flexibly and economically.
